1. CHEMICAL COMPOSITION
“P530” is a special nonmagnetic, austenitic Mn-Cr-N steel with a Nickel-content of ≤2%.
C: 0,05max, Mn: 18.50-20.00, Cr: 13.00-14.00, Mo: 0.40-0.60, N: 0.25-0.40, Ni: 2.00max.
2. MECHANICAL PROPERTIES
Following mechanical properties (tested at room temperature) are achieved by a special cold-working process over the full length of the collar:
Yield Strength (min.): OD less than 4”830 N/mm²
0,2%-offset method: OD 4”to 9 1/4”/ 760 N/mm²
OD 9 1/2”and larger / 690 N/mm²
Tensile Strength: OD less than 4”/ 900 N/mm²
OD 4”and larger / 830 N/mm²
Elongation (min.): 25%
Reduction of area (min.): 50%
Impact energy (min.): 122 J
Hardness Brinell (min.): 285-350 HB
3. MAGNETIC PROPERTIES
Relative permeability: ≤1,001.
4. CORROSION RESISTANCE
- Transgranular SCC: Prevented by special surface treatments (Hammer peening, roller burnishing, shot peening).
- Intergranular SCC: The occurrence of material sensitization is prevented by quenching after warm-forging. Each collar is tested according to ASTM A 262, Pract. A and E, last edition
5. NON-DESTRUCTIVE TESTING
- Magnetic inspection: Drill collars are 100% tested by a proprietary probe-testing process using a Förster Magnetomat 1.782. (“Hot Spot”-test). Magnetic permeability of each collar is certified with the printout of probe-testing.
- Ultrasonic inspection: Each collar is ultrasonically inspected over 100% of the volume according to ASTM E 114, last edition as a minimum level.
6. GALLING RESISTANCE
“P530” is due to the chemical composition and the special cold-working process less susceptible to galling than Cr-Ni steels.
Non-Magnetic material optimized for MWD-collars and stabilizers (higher strength and endurance) is available on special request. P530-Non-Magnetic Drill Collars meet all requirements of API Spec. 7.1, last edition. All tests are carried out according to ASTM-Standards, last editions.

The use and maintain of the sawblade
◎ The carbide tip of sawblade is very sharp, so process of using must be prevent the carbide tip.
◎ PeriodicaI cleaning and support the machine,the spindle’s running tolerance must be less than h7.
◎ The flanges must be parallel to each other,must be of the same diameter 1/3 of the sawblade’s diameter(formuIti—rip saw blade is 1/2.
◎ When instaIIion the sawbIade,it shaII be 5-6 teeth higher than board surface．
◎ Before operation,check the firmly of the sawblade,be sure nobody in front of the machine. Do not feed of operation check whether the machine is good for operaiton. Periodical check the function of the machine,the certicaI jump is less than ±0.02MM,and the flap is less than ±0.01.
◎ After continuous use,must be removed and cleaning the sawblade,get rid of the resin and sawdust of the sawblade of both sides.Other wise it would beinfluence the effect of using the sawblade.
◎ Deposit of the sawblade,must not be layer the sawblade,it is putted in the originaI package inside.
The renovate of the sawbIade
◎ The renovate of the carbide sawblade While it no longer sharpen and the horizontaI piece coarseaess. The power of using sawblade machine obviously Increase. When process materiaI,the materiaI appearred burst. The carbide tip exhaust more than 0.02MM.
◎ For the renovate the sawblade,it shouId be grinding by the a formal company, so be sure the quality of the sawblade after renovating.
